Harold Zinkin

Muscle Beach alumnus Harold Zinkin founded Universal Gym Equipment in 1957 to sell his patented multi-station weight training machine with selectorized weight stacks. By 1960 the company was selling one machine per month, by 1964 one per week and by 1965 one per hour. In 1968 Zinkin sold the company and began a second career developing real estate -- all the while remaining active in the fitness movement he had helped to found.
